Project details
Use this project for one bounded production issue in an existing React, Next.js, or Node application.
Good fits include a broken page, an API or authentication failure, a form or webhook that stopped working, a checkout error, a deployment failure, a performance regression, or a small launch blocker.
I reproduce the issue, confirm the cause and scope in writing, implement the agreed fix, test it, and deliver deployment and rollback notes.
Choose a tier by size. Starter covers one small issue with up to three engineering hours. Standard covers a full rescue with up to eight hours and seven days of regression cover on my change. Advanced adds a second related issue or post-fix hardening such as error tracking, with up to fourteen hours and fourteen days of cover.
If the problem is larger than the package, I stop after the initial investigation, explain what I found, and propose options in writing before any additional work.
This does not cover WordPress theme or plugin work, redesigns, large migrations, malware response, or open-ended maintenance.
You work directly with a full-time software engineer, not an account manager or an outsourced team.

About Anthony
Full-Stack & AI Engineer | React, Next.js, React Native, Node, LLMs
Clearwater, United States - 7:39 am local time
• Production computer-vision system for a high-volume beach rental operation in Clearwater, Florida. Sole engineer. It tracks occupancy across roughly 1,000 rental units for an operation serving about 4,000 guests a day, cut occupancy checks from about two hours to about two minutes, and supported a 17%+ lift in daily rental revenue, including more than $7,000 in added revenue on a $40,000 day.
• MacroScan, an AI nutrition scanner on the iOS App Store. React Native, Expo, camera-first analysis, multi-provider AI routing, subscriptions.
• M.I.L.E.S, an open-source agentic voice assistant with 233 GitHub stars: persistent memory, tool orchestration, and a custom wake-word model trained on 50,000 samples.
• Attendify, a React, TypeScript, and Supabase platform for club administration with QR and location-aware check-in.
I work full time as a software engineer at Sourcetoad, a software consultancy, and reserve 20 to 30 hours a week for freelance projects on evenings and weekends. Freelance work is my own and is separate from my employer. That schedule fits clearly scoped work: a feature, an integration, an AI capability, a mobile release, or a small product delivered in milestones.
What I take on:
• AI and LLM features: chat and assistant features, retrieval over your data, Claude or OpenAI API integration, prompt and tool design, voice interfaces, computer vision
• React Native and Expo: new features, camera and location work, push notifications, in-app purchases, App Store submission
• Full-stack web: React, Next.js, Node, TypeScript, Supabase, Firebase, Postgres, auth, payments, webhooks, third-party APIs, Vercel deployment
• Fixing and finishing an existing codebase when something is blocking your launch
How I work:
1. You describe the outcome you need and your current stack.
2. I tell you plainly whether it fits, and propose a fixed scope with milestones.
3. I write working code, test the affected paths, and deliver with deployment notes.
4. You get direct written updates from the engineer doing the work. No handoffs, no outsourcing.
I am new to Upwork, so my proof lives in public: the GitHub account linked to this profile and the portfolio in my profile links. Before you commit to anything, I will write a short plan for your specific project so you can judge how I think.
To get a useful reply fast, send: what you want built or fixed, your stack, your deadline, and how you will judge that it is done.
